The eldest son of the emperor Louis I the Pious and a grandson of Charlemagne, Lothair was made King in Bavaria after Louis succeeded Charlemagne in 814, and in 817 he was made joint emperor. Under the Ordinatio imperii, a decree issued by Louis in 817 to provide for the unity of the empire after his death, Lothair"s younger brothers, Pepin and Louis (later called the German), were to receive their own kingdoms, Aquitaine and Bavaria, but were to remain under the general suzerainty of Lothair.

Ruler in Italy from 822, Lothair was crowned emperor by Pope Paschal I in 823. He issued the Constitutio Romana (824), affirming imperial sovereignty over Rome and demanding an oath of fealty from the pope. When in 829 Louis I, under the influence of his second wife, Judith, revised the Ordinatio imperii to grant part of the empire previously granted to Lothair to his son by Judith, Charles (later called the Bald), Lothair broke with the imperial government. A palace revolution forced his reappointment as co-emperor in 830, but he was again deposed shortly afterward.

In 833 discontent with the rule of Louis the Pious ended in a revolt of the three elder sons, led by Lothair, and Lothair replaced the deposed Louis. Louis was restored to power the following year, however, and Lothair"s rule was restricted to Italy.

When Pepin died in December 838, Louis I drew up a new partition scheme, dividing the empire, aside from Bavaria and neighbouring areas, which were left to Louis the German, between Lothair and Charles the Bald, with Lothair taking the eastern portion. Lothair was to have the title of emperor, but without the suzerainty over the other princes that had been granted by the Ordinatio imperii of 817.

On Louis I"s death (840), Lothair again claimed his rights under the Ordinatio of 817, but his brothers, Louis the German and Charles the Bald, defeated him at the Battle of Fontenoy (841). The Treaty of Verdun (August 843) left Lothair the Middle Realm of the Frankish dominions, from the North Sea to Italy, while Louis received the eastern and Charles the western territory. The imperial title fell to Lothair.

After granting the government of Italy to his eldest son, Louis II, as early as 844, Lothair partitioned his realm between Louis (emperor from 850) and his two other sons, Lothair and Charles, in 855. Then he abdicated and became a monk.
Verdun, Treaty of

(August 843), treaty partitioning the Carolingian empire among the three surviving sons of the emperor Louis I the Pious. The treaty was the first stage in the dissolution of the empire of Charlemagne and foreshadowed the formation of the modern countries of western Europe. Louis I had carefully planned his three elder sons" inheritances; but from 829 onward his attempts to allocate substantial territory to the future Charles II the Bald, his young son by a second wife, led to revolts by Charles"s half brothers. After Louis"s death (840) open warfare broke out; Louis"s third son, Louis the German, allied with Charles in attacking the eldest son, the emperor Lothair I. Defeated at Fontenoy, in present Belgium (June 841), and driven from Aix-la-Chapelle (Aachen, Ger., 842), Lothair sued for peace. At Verdun (in present northeastern France) the following year, Lothair was confirmed in possession of the imperial title and received Francia Media, a long central strip of territory including parts of modern Belgium, The Netherlands, western Germany, eastern France, Switzerland, and much of Italy. Louis the German received Francia Orientalis, the land east of the Rhine River. Charles received Francia Occidentalis, the remainder of modern France.

Lothaire I was King of Italy (817-855). He became Emperor of the Occident in 840. He was defeated at Fontenoy-en-Puisaye in 841 by the coalition of his brothers, Louis the German and Charles the Bald. At the Treaty of Verdun in 843, he was recognized Emperor. In 855, after dividing his kingdom among his sons, he retired at the convent of Pruem. Upon the death of Lothar, the Treaty of Verdun begins to unravel. In accordance with custom, his Kingdom is divided among his three sons. Louis II, who inherits the imperial title, along with Italy gets Geneva, Lausanne and Sion. Lothar II gets Lorraine and gives the country his name as Lotharingia. Charles gets the Lyonnais and Provence. These issues are only provisional, since they wouldn"t last long.
